Abstract

This paper presents the Physics of current near a cylindrical magnetic interface. In the past, several texts and papers have focused attention on current lines near rectangular structures near conducting or insulating planes and on magnetic fields around solenoids and some other types of current-carrying conductors. This paper explains what happens when a current line passes near a cylindrical magnetic interface. The phenomenon of placing a cylinder in a uniform external magnetic field is explained. The concept of real image and virtual electric currents is analyzed and discussed. The reciprocal point as image on the cylinder is also considered. Also considered and analyzed are phenomena of magnetic force on the cylinder wall and the effective dipole moment in the far-field. This research finds applications in the designs of magnetic systems and coils for electric generators.
